[PATCH net v2 0/6] ipv4: Changes for rt_gateway

	This patchset fixes some problems for the routing caused
by the new rt_gateway semantics. What started as a fix for
IPVS-DR ended as fixes for more problems. To solve the IPVS
problem I decided to name the flag FLOWI_FLAG_KNOWN_NH, so that
we can even get route cached in FNHE or FIB NH.

	Different flag FLOWI_FLAG_RT_NOCACHE could be equally good
for IPVS, we again would be able to use data from fnhe but working
with cached routes should be preferred. If there is no FNHE, the
common case is IPVS to get uncached route, of course, IPVS caches
it itself.

	Patches 1-3 are fixes not related to IPVS problem,
4 and 5 add code that will be used by IPVS in patch 6.

  ipv4: make sure nh_pcpu_rth_output is always allocated
